PASADENA – The kidnapping and rape of a 38-year-old woman this past weekend was unconnected to two other rapes in the same area, police said Monday.

While there are similarities, including the type of vehicle used – a pickup truck – and the fact that all three victims were driven to isolated locations and assaulted, police said they were confident the suspect in the two previous attacks was not involved in the latest.

Last week, police arrested Jason Keith Renaux, 29, of Saugus, whom prosecutors have charged in connection with the alleged rapes, which occurred in November and last month. Renaux remained in custody Monday, awaiting a court hearing.

As he sat in jail, a 38-year-old woman reported she was raped early Friday morning after she got into a man’s white pickup truck. The victim said she was near a bus stop in the 2600 block of East Colorado when she was approached, police said.

The driver took her to an isolated location, sexually assaulted her and dropped her off near La Tuna Canyon Road and the Foothill (210) Freeway, where Los Angeles police found her, officials said.

Also Monday, Pasadena police said they believe the victims in the first two attacks were prostitutes. There was no evidence as of Monday, officials said, that the latest victim also was a prostitute.

The attacker in this past weekend’s assault was described as a white or Latino man, about 45 years old, 5 feet, 10 inches tall and 285 pounds, with brown hair and blue eyes, police said.

He was driving a white pickup truck with a utility box in the bed and an extended cab, police said.

The attack occurred a few blocks east from where the two other women reported being assaulted in a similar fashion in November and December.

Officials also had a word of warning Monday.

“Don’t get into a car and accept rides from strangers and always be aware of your surroundings, even if somebody appears to be friendly,” said Pasadena police spokeswoman Janet Pope Givens. “This is just a very cruel reminder for all of us that those lessons our mothers taught us are very real.”
